Hello. Thanks for writing to us at healthcaremagic
The pattern of hair loss as described by you is suggestive of Androgenetic Alopecia
(female pattern). Hair loss is mainly from the top part of the scalp.
Dandruff may be an additional contributory factor in your hair fall
If I was the treating doctor I would have asked you to use an antidandruff shampoo, once every alternate days.
In addition to this, specific treatment for Androgenetic alopecia would include topical minoxidil
(*Finasteride is to be avoided in child bearing age group women and in case you plan to be pregnant)
Biotin is an added advantage but it has no particular role in androgenetic alopecia. It increases the utilization of proteins in hair growth.
Treatment is long term though results are noticeable by 6 months.
These are all prescription drugs. I would suggest that you visit a dermatologist
in your region for a confirmatory diagnosis as well as appropriate treatment.
